Providing Parameterized QoS for Networks-on-chip by Hybrid Method

摘要

Quality of Service (QoS) is becoming one of the key problems in Networks-on-chip (NoC). In this paper, we propose a hybrid method to provide parameterized QoS for NoC. This method combines the advantages of connection-based schemes and connection-less schemes. Thus, compared with traditional methods, this method guarantees the latency between one flit's generation in the source node and its reception in the destination node, supports a wide range of traffic types such as latency critical, low bandwidth traffic and streaming data which only have bandwidth requirement, and has high link-bandwidth utilization. Moreover, the NoC system which supports the proposed method are implemented. Simulation and synthesis results show that this method can guarantee the bandwidth and latency well and is relatively low-cost.
